Two-dimensional barcode scanners are essential tools used in a wide range of industries for efficiently reading and decoding information stored in barcodes. These devices can be categorized into different types based on their scanning technology and functionality. Understanding the various categories helps users choose the right scanner for their specific needs.
First, there are Linear CCD and Linear Imager scanners. These devices are capable of reading one-dimensional barcodes as well as linear stacked two-dimensional codes such as PDF417. However, when scanning QR codes, they require the entire barcode to be swept vertically across the scanner's lens, which is known as "sweeping reading." These scanners are generally more affordable, making them a popular choice for basic applications.
Second, Laser Readers with Grating technology are another common type. They can also read one-dimensional and linear stacked two-dimensional codes. Unlike the sweeping method, these scanners use a grating element to perform vertical scans automatically without manual movement. This makes them faster and more efficient in certain scenarios.
Third, Image Readers are more advanced and versatile. They use an area array CCD camera to capture the entire barcode image, allowing them to decode both one-dimensional and all types of two-dimensional barcodes. This makes them ideal for complex or high-volume scanning tasks where accuracy and speed are critical.
In addition to the scanning technology, two-dimensional barcode readers can also be classified based on their working mode. They include handheld, fixed, and flat scan models. Handheld scanners are portable and commonly used in retail or warehouse environments. Fixed scanners are installed in specific locations, such as at checkout counters or conveyor belts, while flat scan models are designed for surface scanning in industrial settings.
Although two-dimensional barcode recognition devices have some limitations in terms of reading speed and accuracy under certain conditions, they are still highly effective for most standard applications. Moreover, all of these devices can reliably read one-dimensional barcodes, ensuring compatibility with existing systems.
Whether you're looking for cost-effective solutions or high-performance options, choosing the right two-dimensional barcode scanner depends on your specific requirements, including the type of codes you need to read, the environment in which it will be used, and your budget.
